Description

[Detailed Description of the Invention] <Industrial field of application> The present invention relates to a simple polishing machine with a round blade used for a cooking cutter or the like.

<Prior art> Needless to say, the blade of a cooking cutter or the like should be in a state where it can be cut well at all times, but in the past, there was no simple polishing machine that could be easily polished each time it was used, so it is quite expensive. Either an expensive full-scale polisher was installed or the outside was sharpened.

<Problems to be Solved by the Invention> An object of the present invention is to provide a round-blade polishing machine that is simple, inexpensive and inexpensive, and that can obtain the sharpness obtained by polishing the return caused by polishing. It is in.

<Means for Solving the Problems> In the polishing machine of the present invention, a round blade mounting table is integrally formed on a large gear rotatably mounted on a base by a vertical tube, and the mounting table is projected from the upper surface of the mounting table. A center hole of a round blade can be fitted into the end of the vertical tube body, and a locking hole that matches the mounting hole of the round blade is formed in the mounting table, and the vertical tube and the locking hole are respectively formed. A rotation transmission member having a center rod and a locking rod that can be fitted is provided, and a small gear integrated with a grinding wheel is inserted into an inclined spindle attached to a base to mesh with the large gear. Another small gear and a grindstone which can be freely engaged and disengaged by male and female shaft couplings are inserted into a vertical support shaft erected on the base, and the small gear is meshed with the large gear.

<Operation> The round blade on the mounting table is connected by the center rod and the locking rod of the rotation transmission member, and the rotation of the rotation transmission member causes the rotation of the round blade. Since the grindstone is fitted into the inclined support shaft attached to the base, the lower outer edge of the round blade is ground, and another grindstone rides on the upper outer peripheral portion of the round blade to take back.

<Example> A center hole B and a mounting hole C are formed in a round blade A to be polished (see FIG. 4).

The first embodiment of the polishing machine of the present invention for polishing such a round blade A
Shown in the figure. In FIG. 1, a large gear 2 having a mounting table 4 with a round blade A at the upper portion is rotatably attached to a base 1 by a vertical tube body 3. The end portion of the vertical tube body 3 having a size compatible with the center hole B of the round blade A is made to slightly project from the upper surface of the mounting base 4, and the mounting table 4 has a size compatible with the mounting hole C of the round blade A. The locking hole 5 is formed. The rotation transmitting member 7 having the handle 6 includes a center rod 8 that can be fitted in the inner hole portion of the vertical tube body 3, and a locking rod 9 that can be fitted in the locking hole 5 of the mounting base 4. The gear wheel 2, the circular blade A, and the rotation transmitting member 7 are freely engaged and disengaged.

A grinding wheel 10 for polishing the lower outer peripheral portion of the round blade A is formed integrally with a small gear 11 which can mesh with the large gear 2. The small gear 11 formed integrally with the grinding wheel 10 is a convex portion formed on the upper surface of the oblique block 12 fixed to the base 1.
The tilting support shaft 14 is fitted and inserted so as to ride on the adjusting plate 15 attached to the tilting support shaft 13 and the tilting support shaft 14, whereby the small gear 11 meshes with the large gear 2 at an angle. The adjustment plate 15
As shown in FIG. 3, there are three hole members 17, 18, and 19 having different heights, which can be fitted into the convex portion 13 of the oblique block 12 and the inclined support shaft 14.

On the base 1, a vertical support shaft 20 in which a small gear 21 that meshes with the large gear 2 is fitted is provided upright. The grindstone 22 for removing the return generated by the grinding with the grindstone 10 is formed separately from the small gear 21. However, the pinion 21 and the grindstone 22 have a male and female shaft coupling 23.
Is provided so that both can be engaged and disengaged.

Explaining how to use this round blade grinder, first, depending on the size of the round blade, holes 17 and 1 of three heights of the adjusting plate 15 are provided.
Decide which of 8 and 19 to use, attach the adjustment plate 15, then insert the integrated piece of the grinding wheel 10 and the small gear 11 into the inclined support shaft 14, and insert the center hole B of the round blade A into the vertical pipe. The round blade A is fitted on the end of the body 3 and set on the mounting table 4. Round blade A at this time
Pay attention to the front and back of. Subsequently, the rotation transmission member 7 is attached to integrally connect the large gear 2, the round blade A, and the rotation transmission member 7. Finally, the grindstone 22 is fitted into the vertical support shaft 20 in which the small gear 21 is fitted and brought into contact with the front side of the round blade A, so that the male and female shaft couplings 23 are properly engaged. After that, the handle 6 may be rotated to rotate. The round blade A is polished by the grindstone 10 for polishing, and the return is taken by the grindstone 22.

<Effect of Device> Since the device of the present invention is configured as described above, it is very easy to attach and detach the round blade A, and to use it, water the grindstones 10 and 22 and rotate the rotation transmitting member 7. It is simple enough for anyone to use. Moreover, it is very convenient that the grindstone 22 can be placed on the upper outer peripheral portion of the round blade A by the male and female shaft couplings 23 and can be simultaneously returned when polishing is performed.
